I will develop firmware and pcb design for esp32 stm32 arduino embedded projects

Looking for a dependable embedded systems engineer to bring your ESP32, STM32, or Arduino-based project to life? You're in the right place.

I'm an Embedded/Electronics Engineer with hands-on, real-world experience developing firmware and custom PCBs for client hardware products. I handle the full process from schematic capture and PCB layout to firmware development and testing delivering a complete, working embedded solution.

What I offer:

• Custom PCB layout and schematic creation (KiCad / Altium)
• Firmware development for ESP32, ESP32-S3, STM32, and Arduino platforms
• RTOS-based firmware architecture for real-time, multi-tasking applications
• Wireless connectivity implementation WiFi, Bluetooth/BLE, MQTT
• Sensor and peripheral driver integration
• Power supply design AC-DC and DC-DC conversion circuits
• Battery-powered builds (Li-Po/Li-ion charging, USB-C power input)
• Design for Manufacturing (DFM) checks, BOM preparation, and Gerber files

Why choose me:

• Practical experience building both hardware and firmware for real client products, not just tutorials or hobby projects
• Comfortable handling the full stack from PCB to working firmware so you don't need to coordinate multiple freelancers
